The compositions presented in this portfolio are unified by a common underlying theme: the idea of silence in music. The works were written between October 2012 and August 2015 during the course of my research. They were conceived as part of my exploration of three silence-related areas: the uses of silence in music; the ways of effecting a perception of silence musically; and an indeterminate approach to placing silence in a musical work. Some pieces seek to explore one major idea while the purposes of others may be manifold. But in all these compositions, silence emerges as an integral part of the overall musical structure.
